cRo'ss-hEAREB. 4

To all wlimln' may concern Be it known that I, JoiiN M. RonLr rNc, residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Tmproveme'nts in CrossBearers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is'notlimited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to person skilled in the art.

-In said drawings:.Figure 1- is a transverse sectional view :of a car under-frame showing the improved cross-bearer in elevation with thelongitudi'nal; sills of the car in section. F i-g. 2 is a view taken transversely of the center sills showing the manner-of inserting the diaphragm chair hereinafter more fully described, and F ig. 3 is a side elevational view of the structure shown in Fig. 1.

The object of the invention is to per mitthe use of a very deep center sill in car construction with relatively shallow pressed dia'phragms cooperating therewith, which pressed diaphragms are supported upon a suitable diaphragm chair carried above the bottom flanges of the center sills, which sills are slotted for the passage through the web thereof of such diaphragm chair, so that'diaphragms of greater or less depth and diaphragm chairs of suitable size may he used with sills of the same depth.

Referring to the parts: F indicates the center sills, which are preferably spaced apart, as shown in Figs. 1 and 2, andare provided" withf 'tiheweb port-ions s'hown ..in section in said figures, with top flanges-H connected directly to the webs of said sills,

the diaphragms Band the tops of the bottom sill flanges G, so that the outstanding lateral extensions 2 of the diaphragm chair I have a firm support below the horizontal portion 1 of the diaphragins. B. .It will be noted that below the tops of the sill flanges G, and between the vertical legs of the inner of such flanges, the diaphragm chair S I extends downwardly, so that its bottom flange 3 may rest upon the inwardly projecting horizontal legs of the angles G, while through rivets connect the vertical-flange 4 of the diaphragm chair with the web and bottom angles of the center sill. I

Extending upwardly, relatively between the center sills and between the .lower inner cornerportions of the diaphragms B, the diaphragm chair extends, and is provided with offsets or shoulders flanged at 5, through which flanges 5 and through. the inner flanges 6 of the diaphragms B, rivets extend to connect the diaphragm chair. and

said diaphragms.

It is to be noted that while the structure illustrated is that of a conventional crossbearer of a car undcrf rame, the device may be applied to any transversely extending supporting member of a car underfr'ame, one of the principal objects sought being to permit the 'useof-diaphragm chairs of diflerent heights with sills-of uniform depth, I

thereby permitting propersupport for crossbearer diaphragms, as B, cooperating with such sills, which diaphragms maybe of a height suitable when cooperating with the diaphragm chair, to fill the space between the top and bottom center sill flanges at the By using the construction illustrated in the drawings, it will be observed that there is provided a rigid spacing block or filler, interposed between ,the lower portions of the center sills, which spacing block or filler also serves-as a supporting member for the cross-bearer diaphragm, and by reason of the upward extension of the said filler, pro vides a shoulder for the lower inner corner of such diaphragms, to prevent inward compression under stress of lading,

I have illustrated side sills 6 oil form in?" phragms B are tied together at the top by means of the top cover plate- 8, which is riveted tothe outstanding flanges 9 of the diaphragms B, The diaphr'agms B may be flanged entirely around their perimeter, or such flanges may be provided only at the top at-t-he inner edge 10 and the horizontal connected with said. sills.

2. In a device of the character described, spaced longitudinal sills with perforated webs, a diaphragm chair extending through and beyond said sills, said chair serving as,

a-filler between said sills and diaphragms resting on said chair and connected with said sills. p

3. In a device of the character described, spaced longitudinal sills with perforated webs, a diaphragm chair extending through and beyond said sills anddiaphragms restin on said chair and connected with said sil s, saidchair serving as a, filler between said diaphragmsand between said sills.

4:. an article-of manufacture, a diaphragm chair adapted to serve as a filler between-cross bearing diaphragms and adapt ed to be supported by plate girder car sills and provided with lateral extensions adapted to project through the webs of said sills and serve as supports for said cross bearing diaphragms.

' 5. In a device of the character described, spaced longitudinal sills with perforated webs, a diaphragm chair extending through and beyond said siils, saidchair serving as a filler between said sills and diaphragn'isresting on said chair. V

6. As an article of manufacture, a diaphragm chair-having a portion adapted to serve as a filler between spaced center sills and carried by said sills, and having portions adapted "to support spaced diaphragms. 7. 'As an article of manufacture, a diaphragm chair having a portion adapted to serve as a tiller between cross bearing diaphragms'; within the outlines of spaced center sills, and having a portion adapted to serve as a filler between said spaced center Sill. I

8. In it car underframe, a sill, including webs and a plurality of tension members, a diaphragm chair resting on said tension members and extending through the webs of said sills and diaphragins resting on said chair, portions of said-chair spacing said diaphragms and other-portions spacing said members; n

9. In a car underrrame, a sill buying. a web and a tension port1on and means car'- ried by said portion adapted to PrOject through said web and to fit between and support cross-bearing members.

10. In a car underframe, a $111 compr s- .ing a tension member and a vertical web,

a diaphragm chair resting above said tension member and projecting throughi'said web, and a diaphragm resting on said chair and engaging the outer face of said web.

11; In a car underframe, spaced sills, each sill comprising .a tension member and aperforated vertical web, filhngmeans disposed between and supported above said tension" members and adaptedto project ihrou-gh said web to support cross bea'rm members on the outside of said ve'rticalwe s.

12. As an article of. manufacture, a chairhaving a portion adapted to serve as a co'm' pression member between spaced center sills and havinganother portion forming seats above the bottom of said center sills and adapted to support spaced diaphragins.

13. As an article of manufacture, a chair having the form of a Greek cross, portions thereof adapted to serve a's a compression member bet-ween spaced center sills and other portions thereof forming seats adapt-f ed tol support spaced diapli'ragms, and another .portion thereof adapted to serve as the filler between said diaphragmsl In witness whereof I have hereunto set -my hand in the presence of two vitncsses.
